The Detroit Pistons and Sacramento Kings have talked about a potential Josh Smith deal:

Sources close to the situation told ESPN.com on Tuesday that the Pistons have engaged the Sacramento Kings in trade discussions this week that would potentially land Josh Smith in the same Sacramento frontcourt as DeMarcus Cousins and Rudy Gay. Sources say that Smith being swapped in exchange for the combination of Sacramento's Jason Thompson and Derrick Williams is one trade construction that the teams have discussed. Although one source insisted Tuesday that no deal is imminent, another source told ESPN.com that the teams have continued to exchange proposals, with Williams potentially being replaced by another Kings player such as Jason Terry or Carl Landry.

Here's the interesting part for Celtics fans:

Another potential bonus [for the Kings] is Smith's close relationship with Boston Celtics point guard Rajon Rondo, whom Sacramento has reportedly been targeting in trade talks for some time.
